Common Bus Power Supplies

Common Bus Power Supplies use a common rectifier to supply power to the DC bus for all the DC-AC inverters. Power-sharing on the DC bus increases the efficiency of applications where inverters are motoring while others in the same process are generating power.

Our Bulletin 20S SCR Bridge is a non-regenerative DC bus supply that supplies power to AC drives that have a common DC bus input. The supply converts incoming three-phase AC line voltage to a common DC bus voltage. You can configure this supply for stand-alone and master-slave applications.
